agenerase The Aspect Ratio AR is
The different values of AR related to DNA nanoparticle in the different motion modes of the nanoparticle on substrate have been compared in Fig. 11(c)–(e). As is observed, with the increase of AR in both the sliding and rolling modes, the critical force and time of particle movement increase. This finding agrees with the results presented by Moradi et al. (2010).
Fig. 11. Comparing the critical force and time with the mutation rate changes in nanoparticle radius, probe tip radius and aspect ratio, (a): sliding mode of probe tip on particle in the parallel direction to the longitudinal axis, (b): sliding mode of probe tip on particle in the normal direction to the longitudinal axis, (c): sliding mode of particle on substrate in the lateral direction, (d): sliding mode of particle on substrate in the longitudinal direction and (e): rolling mode of particle on substrate.Figure optionsDownload full-size imageDownload as PowerPoint slide
